Chemical Name: 4-Hydroxy-3-methoxy-[(2S,3aR,3bS,6aR,9aR,9bR,10R,11aR)-3a,3b,6,6a,9a,10,11,11a-octahydro-6a-hydroxy-8,10-dimethyl-11a-(1-methylethenyl)-7-oxo-2-(phenylmethyl)-7H-2,9b-epoxyazuleno[5,4-e]-1,3-benzodioxol-5-yl]benzeneacetate
Purity: ≥98%
Biological Activity
Potent analog of capsaicin that is an agonist at vanilloid receptors (Ki = 43 pM). Like capsaicin, it acts as a selective modulator of primary afferent neurons.Technical Data
